Infinite Flyer Recommendations

Hello Guys! I need your advice!
I am about to develop a game which will mostly be like any 3D FPV infinite runner with exception that it will have a character moving up and down and fly instead of running and jumping.Besides i want it to move sideways like in Temple Run but up and down by swiping up and down.Mostly all the assets that i've been looking through are too pain to modify because they are made for the character that is running and jumping and sliding.Any reccomendations about relatable assets or tutorials that will help.
Pretty much any help will do!

 

About the only hard part of an infinite runner is the infinite terrain — particularly in a FPV, you'll need to divide the terrain into chunks and load (or precedurally generate) them as you go. This will be the same for almost any 3D infinite runner, so I would think you could take something off the asset store and adapt it to your needs.
